[0002] A hand dryer is a sanitary appliance used to dry or blow dry hands in the bathroom, and is divided into an induction automatic hand dryer and a manual hand dryer. It is mainly used in hotels, restaurants, scientific research institutions, hospitals, public entertainment venues, and bathrooms in every household. The hand dryer overcomes the shortcomings of existing hand dryers that cannot discharge air in multiple directions, which easily causes the skin temperature of the hands to be too high. It aims to provide a hand dryer that circulates and discharges air in multiple directions. An air guide device is provided at the air outlet of the hand dryer, and air guide blades are provided on the air guide device. The technical solution that the hand dryer circulates and discharges air in an undirectional manner is adopted through the rotation of the air guide device or the swing of the air guide blades. Existing hand dryers, such as the CN201320302Y dry hand washer, are hung on the wall with hooks, or installed on the wall with fasteners such as screws, but the installation method using screws is relatively cumbersome and difficult to dismantle during maintenance. Therefore, it is very important to obtain an installation structure and a hand dryer that are easy to install and anti-theft. Utility Model Content
